Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564092, here are decompositions:

13 + 31564079 = 31564092
41 + 31564051 = 31564092
83 + 31564009 = 31564092
103 + 31563989 = 31564092
113 + 31563979 = 31564092
139 + 31563953 = 31564092
149 + 31563943 = 31564092
151 + 31563941 = 31564092

Showing the first eight; more decompositions exist.
